There is a simple rule for composite objects, such as nuclei or atoms. The rule is that if such an object contains an odd number of fermions, the composite object is a fermion. Otherwise, it is a boson. ...this simple rule doesn't care at all about the number of bosons in the composite object.

In a logically perfect language, there will be one word and no more for every simple object, and everything that is not simple will be expressed by a combination of words, by a combination derived, of course, from the words for the simple things that enter in, one word for each simple component.
Bertrand Russell
You can't please everyone. When you're too focused on living up to other people's standards, you aren't spending enough time raising your own. Some people may whisper, complain and judge. But for the most part, it's all in your head. People care less about your actions than you think. Why? They have their own problems!
